FAN.

. Applicationfil ed October 21, .1925. am-a a. anon.

Thisinvention relates to improvements in fans for usegin frightening and shoeing flies from the. presence of a person while sleeping, the general object being the provision 10f an oscillating arrangement used in conjunction with the fan in sweeping a desiredspace in frightening and shooing the flies therefrom. I i

. Another object of my invention is the provision i'of a governing apparatus operated the speed of the fan so that the noise incident to the operation ofthe same may not disturbthe person asleep. v

-' Wi=ththe above and other objects in view,

the, invention further includes the following novel features, and details of construction,

to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in, theappended claims.

Referring; to, the drawings in detail, whereinlike characters of reference denote corresponding parts,

The segmental gears 24 further include forwar-idly inclined slotted portions 26 upon their veorrespondinginner sides and are of sutlicient; width r-andlength to readily and easily receive any one of a plurality of the pins 19 arranged upon the upper side offthe gear 18 for creating va movement pursuant to moving the gears 24 one toward the other in one simultaneous operation; one of the bushings 25 supporting the segmental gears 24 carries ohannelbar 2.7 land one of the 7 gears 24in order that the bar237 may oscillate therewith, Saidrohannel ban includes a clamping member 28 upon its forward end in supporting ashaft 29 having a, fan, of any suitable type, as indicated at 30, suspended from its under side. A bifurcated arm 31 is suspended from the under side of and a roller 82 rotatably .inounted within its lower free end and adapted to race backward and forward zupoin' an .arcuate track 33 arranged upon the upper side of the top 11. is suspended 'amotor 12 having a relatively It will thlus zbe noted: from the foregoing description and accompanying drawings that when the relatively large gear 13 isqset -in motion the source of momentum trans: mitted by the motor 12, owing to the engage: nae-ntsof the gear 13 with the worm 17 of the gear 16, will in-iturn cause the gear d-8 1130 rotate in one direction, in the rcoursefindi cated by the arrowin Figure 1 ofthe hawings, in order-that the; vertically disposed ins 19 arranged at diametrically opposite sides thereof will, be selectively positioned and engaged within the forwardly inclined slotted portions 26 arranged upon the corresponding and adjacent linnerrsides er "the r 110 sary oscillatory monemientgto thegchannel bar segmental :gears24in; imparting the reces 27 carrying the shatt 29rand-fany30-thereon 2 while the roller 32 tends to supportthe channel bar 27 upon the track It is generally known that when a motor is left to its own propensities it will attain a great rate of speed and develop undue noises, as in the racing of an engine, and in order to provide,

suitable means for use in conjunction with the present entitled invention for governing the speed at which the fan 30 may be oscillated, I provide a shaft il-l having its respective ends journaled within the top 11. and an auxiliary bracket 15 suspended from the under sidethereof and having its upper end fixed to a gear 36 meshing with the gear 18 for imparting the necessary rotary movement to the shaft Bl which in turn has a governing apparatus 37 mounted thereon; the disk 38 carried upon its lower end has its upward vertical movement controlled by a set screw 39 carried upon the inner side of the supporting bracket 35. lhe housing 10 may obviously include a clamp as indicated at 40 for supporting the device as a whole upon a body or shaft as indicated at ll in Figure 2 of the drawings.

In the use and operation of the present invention it is clearly apparent and manifest: that when the motor 12 imparts the neeessary rotary movement to the gear 13 fixed to the armature shaft, not shown, it will in turn impart a rotary movement to the shaft 16 owing to its meshing engagement with the worm portion 17 carried thereon and in so doing the gear 18 rotated to bring the vertically disposed pins 19 arranged upon diametrically opposite sides thereof into selective and continuous engagement within the forwardly inclined slot-ted portions 26 arranged upon the corresponding inner sides of the segmental gears il-l whereby the channel bar 2? will impart the necessary oscillatory movement to the shaft 29 carrying the fan 80, owing to its fixed engagement upon one of the bushings 25 supporting the segmental gears 24.

The relative attainment and rate of speed of the motor is regulated by the governing apparatus, as described and illustrated,

whereby the fan 30 and motor mechanism may in no way create a nuisance by the noise attained during the operation of the invention.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described claimed is 1. A fan comprising a housing, a top therefor, a motor arranged within the housing, a relatively large gear mounted upon the top and operable by said motor, pin members carried upon the face of the gear, a
